IMPROVEMENT IN PHQTOGRAPHiC PRINTlNG-FRAMES.

Specification forming part of Letters Patent No. 19!,906, dated June 12,1877 application filed February 22, 1877.

10 all whom it may concern:

Be it known that we, HARVEY L. WALTER and REUBEN DUERIN, of Manchester,in the county of Delaware and State of Iowa, have invented certain newand useful Improvements in Photographic Printing and Printing-Frames andwe do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

Our invention relates to photographic printing-frames; and it consistsin a combined printing, tinting, and vignetting frame, as will behereinafter more fully set forth.

In the annexed drawing, which fully illustrates our invention, Figures 1and 2 represent front views closed, and Figs. 3 and 4 represent frontviews open, of our invention. Fig. 5 represents a side view closed, andFig. 6 is a central vertical section of the same on line w m. Fig. 7represents a detail view.

A represents a frame of suitable dimensions, in which the paper ortissue support B is fastened by means of a pivoted springbar, 0, theends whereof are held under suitable projections on the frame A. Thesupport B is formed on the back with lugs or projections, d, fitting incorresponding recesses in the frame, and the support has also pins 0, toenter corresponding holes in the frame, thereby insuring the sameposition of the support in the frame under all circumstances.

To one side of the frame A is, by means of double-acting hinges h h,hinged a frame, D, for containing the negative G, which is held firmlyin place by an auxiliary interior frame, E, one side whereof is placedunder plates 2' i, or hinged, and the other side held by a button, k.

A similar frame, D, is hinged, in like manner, to the other side of thecenter frame A, and this frame contains a clear glass plate, I, held inthe same way by an interior frame, E.

The sensitive-paper or tissue is held to the support B by pivoted clampsff, as shown.

This combination-frame is for the photographic printing, tinting, andvignetting of carbon or other pigmented tissues, sensitive paper, orother sensitive surfaces of a flexible character, on a clamped support,in medallion, arch top, or other fancy design, by masking the backgroundof the negative G, such mask, as shown at m, being adjusted to'a patternof the figure-mask imposed on the support B. This figure-mask n isplaced on the glass plate I, and must be adjusted to the pattern abovementioned on the support B. Now, when the picture so masked is printed,the negative-frame D is folded beneath the support-frame A, and theframe I), with the glass plate I and figure-mask n thereon, (which plateand figure-mask may be designated as a tinter,) is then brought into theposition formerly occupied by the negative, when the border may besubjected to the action of the light.

Ordinarily photographic prints are made in one frame, and then tinted inanother, which necessitates two adjustments of the prints before theprinting operation is complete. Again, in printing carbon tissue aneffect of light is obtained which cannot be seen until the tissue isdeveloped. Consequently the printing of pigmented tissues requires, bythe old method, a very nice adjustment of the tissue to the top and sidelines of the background mask in frames as now used; then a very niceadjustment again when placed in the tinting-frame. Hence, to produce adozen pictures in carbon, twenty-four nice adjustments of the necessarytissues are required.

With our invention it is only necessary to adjust the negative andbackground mask to the pattern on the tissue-support, then adjust thefigure-mask on the tinting-glass to the same pattern, when we areenabled to put the paper or tissue in position, and print and tint asmany duplicates as are desired, by merely taking the picture off whenfinished, and supply-its place with fresh material without any furtheradjustment of the negative, masks, &c.

It will then be seen that we print the picture and tint the borders andbackground on the sensitive material without removing said material fromits support in the frame, and repeat the operation of producingduplicates with no further adjustment of masks or negative other thanthe primary one, except in the renewal of fresh material on which tomake said duplicates.

The hinges h h are preferably made doubleacting, so as to giveathree-part frame, which folds compactly, and admits of the position ofthe top and bottom parts being reversed.

D, whereby both the negative-frame and tinting-frame can be brought overthesu pportframe, for the purposes herein set forth.

2. The negative-frame D' and tinting-frame D, connected to thesupport-frame A by means of double-acting hinges h h, whereby saidframes D D may be turned on top of or beneath the frame A, substantiallyas and for the purposes herein set forth.

In testimony that we claim the foregoing as our own we affix oursignatures in presence of two witnesses.
